DDC (Display Data Channel) and X-Rite’s “ADC” (Automatic Display Calibration) protocols are designed to simplify and streamline the display calibration process. Not all DDC enabled monitors work well with ADC. There are some limitations that can sometimes be attributed to the graphics card, connection type, the monitor’s implementation of DDC, as well as ADC functionality.

If there is a suspected problem with the way ADC is handled by a video system (display-video card-cabling), try the following suggestions:

Check to see if the display’s menu/OSD (On Screen Display) has “DDC” or “DDC/CI” enabled or turned on. If so, disable it or turn it off in the display’s menu/OSD. Many displays will have DDC/CI enabled by default.
